“…The signs and symptoms of DVT are non-specific and may be associated with other lower extremity disorders, including lymphedema, PTS, superficial venous thrombosis, cellulitis, musculoskeletal trauma, and Baker’s cysts. Among patients referred to the vascular laboratory for exclusion of DVT, only 12%–31% will have a positive ultrasound (US) study [ 10 – 12 ].The most common presenting symptoms have a wide range of reported sensitivities and specificities: calf pain, sensitivity 75%–91% and specificity 3%–87%; and calf swelling, sensitivity 35%–97% and specificity 8%–88% [ 13 – 18 ]. None of the signs or symptoms is sufficiently sensitive or specific, either alone or in combination, to accurately diagnose or exclude thrombosis [ 19 ].…”

Lower extremity deep vein thrombosis is a serious medical condition that can result in death or major disability due to pulmonary embolism or post-thrombotic syndrome. Appropriate diagnosis and treatment are required to improve symptoms and salvage the affected limb. Early thrombus clearance rapidly resolves symptoms related to venous obstruction, restores valve function and reduces the incidence of post-thrombotic syndrome. Recently, endovascular treatment has been established as a standard method for early thrombus removal. However, there are a variety of views regarding the indications and procedures among medical institutions and operators. Therefore, we intend to provide evidence-based guidelines for diagnosis and treatment of lower extremity deep vein thrombosis by multidisciplinary consensus. These guidelines are the result of a close collaboration between interventional radiologists and vascular surgeons. The goals of these guidelines are to improve treatment, to serve as a guide to the clinician, and consequently to contribute to public health care.
